ExploraTour - Looking at the World in a Different Light

If you could see beyond red light, how would the world look?
Light beyond red is called infrared. Infrared light is given
off by warm objects ... like you. This type of light is
invisible.
Pretend your eyes can now see infrared light and look at the
sleeping man in the picture. With your infrared vision, you know
that the hottest parts of the man's body are his
hands and feet. You don't even need to ask him.

How do you know this?
It's because in the picture,
his hands and feet are the brightest color (white).
